Multiple Vulnerabilities in VMware products 

Indian – Computer Emergency Response Team (https://www.cert-in.org.in)

Severity Rating: CRITICAL

Software Affected

VMware ESXi 8.0, 7.0

VMware Cloud Foundation 5.x, 4.5.x, 9.0.0.0

VMware Workstation 17.x

VMware Fusion 13.x

VMware Tools 11.x-13.x

VMware vSphere Foundation 9.0.0.0

Overview

Multiple vulnerabilities have been reported in VMware products, which could allow a remote attacker to execute arbitrary code on the targeted system.

Target Audience:

Enterprises and large organizations, cloud service providers, and industries with IT environments utilizing VMware products.

Risk Assessment:

High risk of sensitive data exposure and arbitrary code execution.

Impact Assessment:

Potential for host system compromise through virtual machine escape.

Description

VMware provides virtualization software solutions that enable organizations to create and manage virtual machines (VMs), allowing multiple operating systems to run on a single physical machine.

These vulnerabilities affect VMware products due to an integer overflow in the VMXNET3 virtual network adapter, an integer underflow in VMCI (Virtual Machine Communication Interface), a heap-based buffer overflow in the PVSCSI (Paravirtualized SCSI) controller, and the use of uninitialized memory in vSockets. An attacker with local administrative privileges within a guest virtual machine could exploit these vulnerabilities to execute arbitrary code on the host system.

Successful exploitation of these vulnerabilities could allow a local attacker to achieve code execution on the underlying host, leading to potential system compromise.

Solution

Apply appropriate updates as mentioned by the vendor.
